摘要

本文介绍了一种新的动态四元CMOS技术。仅使用没有阈值修改的标准增强mosfet是开发的目标之一。两个连续的逻辑电压之间的差必须大于mosfet的阈值电压。因此,可以达到高噪声裕度。本文给出了连接四元电路和二进制电路的动态电路。此外,还给出了四元或与门。结合文字算子,所有的四元逻辑函数都可以用该技术实现。此外,给出了四种模糊逻辑电路,即有界和电路和有界差分电路以及差积电路和差积电路。

Quaternary dynamic differential logic with application to fuzzy-logic circuits
This paper introduces a new dynamic quaternary CMOS technique. Using only standard enhancement MOSFETs with no threshold modifications was one aim of the development. The difference between two successive logical voltages has to be greater than the threshold voltages of the MOSFETs. Thereby, a high noise margin can be reached. The paper shows dynamic circuits for connecting the quaternary circuits with binary ones. Furthermore, quaternary OR- and AND-gates are given. In connection with literal-operators, all quaternary logic functions can be realized with the technique introduced. In addition, four Fuzzy-logic circuits are shown, namely a bounded-sum and a bounded-difference circuit as well as a drastic-product and a drastic-sum circuit.
